Paw Trail #237: 7x7 Path Puzzle (Hard)
hardDrag from 1 to 8 — fill every square
A 7x7 path puzzle: visit every square exactly once, hit the numbers 1 to 8 in order, and never cross a wall.
- Draw one path that moves up, down, left or right.
- Pass through every square exactly once.
- Visit the numbers in order, starting on 1 and ending on 8.
- You can’t cross a wall. Drag back (or tap an earlier square) to undo.
The route, square by square
Squares are written as R<row>C<column>, counting from the top-left.
R6C2 → R6C1 → R7C1 → R7C2 → R7C3 → R7C4 → R6C4 → R6C3 → R5C3 → R4C3 → R4C2 → R5C2 → R5C1 → R4C1 → R3C1 → R3C2 → R2C2 → R2C1 → R1C1 → R1C2 → R1C3 → R2C3 → R3C3 → R3C4 → R4C4 → R5C4 → R5C5 → R4C5 → R4C6 → R5C6 → R6C6 → R6C5 → R7C5 → R7C6 → R7C7 → R6C7 → R5C7 → R4C7 → R3C7 → R2C7 → R1C7 → R1C6 → R1C5 → R1C4 → R2C4 → R2C5 → R3C5 → R3C6 → R2C6
About this puzzle
This 7×7 grid has 8 numbers and 8 walls, and exactly one route fits all of them. The path starts at R6C2 and finishes at R2C6.
Squares with a single open neighbor must be the end of the path, so check whether that is the last number or something is wrong earlier on.
This type of puzzle is a Hamiltonian path with waypoints, here with paw prints and walls.
